Background: In our study, we aimed to test the efficacy and safety of Trans-Perineal Laser Ablation of the prostate (TPLA®) in the surgical treatment of high-risk Benign Prostatic Obstruction (BPO) patients.
Methods: We defined a high-risk BPO patient as an elderly man affected by severe comorbidities, among which coagulation issues due to pre-existent medications or diseases. From October 2020 to June 2022, we prospectively enrolled high-risk patients affected by a moderate to severe and/or complicated BPO condition. The analysis of the efficacy of the Trans-Perineal Laser Ablation was defined as the primary endpoint of the study. Secondary endpoints were post-operative surgical complications and patient-reported quality of life.
Results: Globally, 40 consecutive patients were enrolled. Median (IQR) age was 80 (72.5-84) years. Median Charlson Comorbidity Index was 6 (5-7). Median prostate volume was 38 (30.5-73) cc. In all cases, a TPLA® procedure was performed under local anesthesia, and patients being discharged within the same day of the procedure. A progressive reduction of median prostate volumes was reported at 3 and 6 months post-operatively, compared to baseline [38 (30.5-73) vs 35 (26-49) vs 34 (28-49) cc, p < 0.001]. Median International Prostate Symptom Score (IPSS) improved accordingly [25 (19-30) vs 10.5 (7.5-13) vs 8 (6-11.5), p < 0.001]. A permanent bladder catheter was successfully removed in 13 out of 23 (56.5%) cases. Within 90 days from surgery, 19 (47.5%) patients experienced at least one surgical complication. According to the Clavien-Dindo classification, complications were classified as grade I in 16 (40%) cases, grade II in 9 (22.5%), and grade III in 1 (2.5%). We did not observe any grade IV or V complications.
Conclusions: The Trans-Perineal Laser Ablation of the Prostate is a feasible, safe, and effective Minimally Invasive Surgical Technique, when offered to elderly, high-risk patients affected by severe Benign Prostatic Obstruction.

Introduction: Although photodynamic therapy (PDT) shows considerable potential for cancer treatment due to its precise spatial control and reduced toxicity, effectively eliminating residual cells under hypoxic conditions remains challenging because of the resistance conferred by these cells.
Methods: Herein, we synthesize an amphiphilic PEGylated polyphosphoester and present a nanocarrier (NP) specifically designed for the codelivery of hydrophobic photosensitizer (chlorin e6, Ce6) and hypoxia-activated prodrugs (tirapazamine, TPZ). We investigate the antitumor effect of NP on both cellular and animal level.

Background Fracture of nickel-titanium (Ni-Ti) instruments in root canals is commonly associated with compromised outcomes in endodontic treatment. There is no single, universally accepted approach for managing this complication. The objective of this study is to evaluate the effectiveness of an Nd: YAP laser-assisted protocol in removing fractured Ni-Ti files in teeth with minimal root curvature (less than 15 degrees).

Background: Developing carrier-free nanomedicines via self-assembly of two antitumor drug molecules is a potential strategy for enhancing the combination treatment of tumors. Similarly, conventional chemotherapy combined with photodynamic therapy may synergistically improve the antitumor effect while minimizing the adverse reactions associated with antitumor treatment. Hyaluronic acid (HA) can bind to overexpressed HA receptors on the tumor cell surface, increasing cell internalization and resulting in good tumor-targeting properties.

A novel Pompe rat model ( ) was used to test the hypothesis that neonatal gene therapy with adeno-associated virus serotype 9 (AAV9) restores cardiorespiratory neuromuscular function across the lifespan. Temporal vein administration of AAV9-DES-GAA or sham (saline) injection was done on post-natal day 1; rats were studied at 6-12 months old.

In this study, we attempt to illustrate fossil vertebrate dental tissue geochemistry and, by inference, its extent of diagenetic alteration, using quantitative, semi-quantitative and optical tools to evaluate bioapatite preservation. We present visual comparisons of elemental compositions in fish and plesiosaur dental remains ranging in age from Silurian to Cretaceous, based on a combination of micro-scale optical cathodoluminescence (CL) observations (optical images and scanning electron microscope) with minor, trace and rare earth element (REE) compositions (EDS, maps and REE profiles), as a tool for assessing diagenetic processes and biomineral preservation during fossilization of vertebrate dental apatite. Tissue-selective REE values have been obtained using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS), indicating areas of potential REE enrichment, combined with cathodoluminescence (CL) analysis.
